Russia's Top Car isn't the only tuner tampering around with the recently revealed, but not yet available, 2011 BMW 5-Series sedan. So is Racing Dynamics, otherwise known as RDSport in the USA. The Italian tuner that specializes on BMW products, has released a teaser photo (chop) and preliminary specs on the 535i R35 and the 550i R50S that will both receive a bevy of performance and styling mods.

While Racing Dynamics has not yet released specific details on the engine upgrades, the tuner said that the 535i R35's 3.0-liter inline-six with the twin-scroll turbocharger will receive an extra boost to produce 410HP and 383lb-ft torque for an estimated 0-60mph (96km/h) sprint time of 5.3 seconds, or 0.7 seconds faster than the standard 306HP 535i.

The range-topping 550i with the R50S package will deliver an output of 620-horsepower versus the factory model's 407HP 4.4-liter twin-turbo V8.

In addition to the engine mods, the Bavarian sedans will also benefit from a custom made exhaust system, a high performance braking system, a new rear-locking differential and a retuned and lowered suspension with new gas struts for the front axle and gas-pressurized shock absorbers for the rear.

The package will be rounded off with new 21-inch lightweight alloy wheels, an aero kit and various options for the interior including special trim inlays.

More details are expected to be released within the next few weeks.
